FAQ

A watermaker is a (partially) automated machine which converts brackish and salt/sea water into fresh and clean drinking water. This way, all water used on board, is taken care of by one machine. The Sea Recovery range of watermakers all use the reverse osmosis technique to purify the water.

Reverse Osmosis is a water purification technology that uses a semipermeable membrane to remove Viruses, Bacteria, sugars, soluble salts (ions), Metal Ions, and larger particles from sea water to produce drinking water. For more go to the page about Reverse Osmosis.

For choosing the right type of watermaker that fits your needs or demands, a number of things are important to keep in mind. The number of people on board, the size and the type of vessel are a few indications to start with.

For personal advice on wich type of watermaker fits your needs best, contact Sea Recovery consultant Marcel Vink at Theunissen Technical Trading BV by mail: m.vink@tttbv.com or phone: +31 (0)24-3667473

Every watermaker needs periodically maintenance which includes changing filters (consumables) and flushing the system. The best way to maintain your watermaker system is to make sure the filters are changed on time when they are poluted, flushing the system automatically after use and cleaning is performed every time it is needed.

At Theunissen Technical Trading BV we have an inhouse service department. Almost all spare parts and filters are available from stock. This way, we always find a solution to repair or fix a malfunctioning watermaker.

Yes. Brackish water will not harm the reverse osmosis membrane element nor the system. The Sea Recovery Aqua Matic and Ultra Whisper series self adjusts its operating pressure to compensate for high and low salinity feed water while producing the correct amount of great tasting product water. The Aqua Whisper and Aqua Mini series operating pressure may be manually adjusted for operation in brackish water conditions

No. Besides AC watermakers we also offer 12VDC and 24 VDC watermakers, this means that you don’t need a generator.

Yes. You can clean the prefilter elements several times before you have to replace them. It is important that you use only Sea Recovery prefilter elements, these are engineered with special materials and a specific micron rating.

String wound and fiber type filters are designed for the photographic industry and will last only 1/10th the time of the proper Sea Recovery filter element. Using string wound or fiber type filter elements will require ten times more maintenance and cost ten times more in element changes. Swimming pool filters and household under-the-sink filter elements are made from the wrong material; they are not of the proper micron rating and will fall apart in seawater which will cause fouling and damage to the reverse osmosis membrane elements.
